| Popis: | This research focuses on the structural study of three folded horizons of Fat'ha, Jeribe, and the Euphrates in Judaida structure, Northern Iraq. Depth contour maps for three horizons using the time and velocity data called from seismic surveys. Seismic interpretation suggests that Judaida structure is a positively inverted structure. It is an anticline on the level of Tertiary and the top and an extensional structure on the level of pre-Tertiary sequence. Judaida structure is an asymmetrical longitudinal anticline; its Northeastern limb is steeper than its Southwestern limb. The axis of the anticline and the major normal faults are both trending toward the Northwest. The normal fault picked influencing only the pre-Late Cretaceous sequence where is the folding affected the whole sequence; of the extension forces, it affected the region during that period. Late Pliocene compressions resulted in folding and reverse faulting of the whole sequence and inversion of movement along the pre-existing normal faults. The resulted faults are called inverted faults. |
